This is one of those recipes I eyeballed it for.
Clean and dry the meat.
Pierce
the meat, so the marinade can penetrate well.
First marinade is lemon juice and salt
for 10-15 minutes.
Main Marinade is
yoghurt, / curd / dahi
chilli powder
jeera
powder
coriander powder
amchur
garam masala powder
ginger paste
garlic paste.
Marinate in the fridge overnight or longer.
Take out the meat from the fridge and bring it to room temperature.
Put just the meat in a preheated oven and roast at 160C fan oven/ 180C regular oven for 30
mins per half kilo.
Take out the meat from the oven, add the rest of the marinade and
pop in the oven for another half hour.
If you feel that it's burning on
the thinner end, cover that with foil.
Rest for 10-15 minutes in a warm
location before slicing.
I added the mushrooms in the last 10 minutes of
cooking.
If you want to make this with potatoes, you will need to add them earlier.
